Trains, trade and transaction costs : how does domestic trade by rail affect market prices of Malawi agricultural commodities?
Zant, Wouter - 2015
We measure the impact of low cost transport by rail in Malawi on the dispersion of agricultural commodities prices across markets, by exploiting the quasi experimental design of the nearly total collapse of domestic trade by rail in January 2003, due to the destruction of a railway bridge at...
